Quick Answer & Explanation
49 is the only

The answer to this riddle is 49 is the only. Difficulty: Hard · Solved by 12,361 puzzle lovers.

49 is the only candidate, but 49 = 7 x 7, so it is divisible by 7. Actually, re-checking: 1 fits all criteria (not prime by convention, odd, not divisible by 3, 5, or 7, and less than 50). The answer is 1.
